1 Claim.

My invention relates to movable displays that are particularly useful for the displaying of maps, drawings of right of ways for railroads, transmission lines, highways, and pipe lines.

I The device is well adapted for use in hotel lobbies and in any and all places where it is needed, or found desirable, for the placing in an accessible form delineated data that may be inspected and observed in a convenient and accessible form.

The invention is comprised of a fabricated framed structure having a cabinet mounted relative to the frame that is .adapted for being raised and lowered within suitable guideways. The

display carries a pair of winding drums adapted for being spring tensioned and adjacent thereto a pair of driving drums. The driving drums being adapted for being adjusted in their spaced relationship to compensate for the slip of the delineated sheet when the cabinet is disposed in a vertical position.

The device may be hand, or power manipulated. Means being provided to rotate, or partially rotate, the display relative to the frame to render the same more accessible and to facilitate inspection of any part of the delineated surface with greatest comfort and convenience to the user.

The primary purpose and object of my invention is to provide a display for maps that will permit greatest convenience to the user.

. A further object of my invention consists in providing a frame that may be permanently positioned and having adjustable and rotatable display winding mechanisms associated therewith that may be adjusted vertical and rotated about a central support and that may be manually or power driven to place that portion of the desired delineated surface into View of theuser at the will of the operator.

Heretofore it has been the general custom to place one, or more large maps in a cabinet that will place in view the entire map surface. In large maps it has often been very inconvenient for the user of the map to inspect the'top and bottom areas of the map. Through the use of my new and improved device I provide a mechanism that makes accessible, for inspection, the particular area of the map that the user is particularly interested in and provide means for placing the same in an easy accessible position to the user of the same.

In drawings, delineating right of ways of railways, highways, transmission lines, pipe lines and the like the same often cover many miles in area, and it is often necessary to have the same delineated upon long rolls of drawingsand it is necessary to unroll the drawings, or tracings delineating the same. Through the use of my new and improved device the strips may be mounted parallel to each other upon the drums,

or rollers and place the same in useable form so that any portion of the drawings may be readily and instantly inspected. Each of the cabinets may have mounted thereupon desired data and be replaceable within the frame as desired and stored away in vaults, or other accessible places when not in use.

A further object of my invention consists in so constructing my device that they will have a minimum first cost and that they will be so constructed that they will give a minimum of operating annoyance.

With these and incidental objects in view, the invention consists in certain novel features of 7 construction and combination of parts, the essential elements of which are set forth in the appended claim, and a prefered form of embodiment of which is hereinafter shown with reference to the drawings which accompany and form a part of this specification.

Fig. 10 is a fragmentary, rear view, of the primary frame and of the cabinet supporting mechanism; The cabinet is-adjusted for'being raised and lowered relative to the frame. The same being taken on line 10-40 of Fig. 2, looking in the direction indicated.

Fig. 11 is a sectional, rear view, of the cabinet shown removed from the frame. The same being taken on line 1111 of Fig. 2,looking in the direction indicated.

Fig. 12 is a fragmentary, plan view, of one end of the cabinet illustrating an adjustable compensating roller, or drum supports disposed in one end of the cabinet, the purpose and object of which is to provide an adiustable compensator for spacing the ends of the driving and winding drums apart to maintain the delineated surface in desired placement as the same is .wound across the face of the cabinet.

Like reference characters refer to like parts throughout the several views.

I preferably form my device of a frame comprised of a pair of vertical rails 1 and 2. The rails being spaced apart by suitable cross members .3 and 4. The rails being suiiiciently long tosupport a cabinet 5 therein. The cabinet 5 is positioned and connected to the frame that the same'may be raised and lowered within theframe, or rotated relative theretoabout a central journalsupport. A spider frame Shas shoes .7 and 8 disposed at either side thereof. The shoes are supported by arms 9, 10, 11 and 12, that run from the central hub of the spider to the shoes. Thezarms being so ribbed as to reduce the cost The rails have guide bars 13 and 14 that are parallelly disposed with each other .and that are spaced apart to form raceways into which the respective shoes of the spider 6 areadapted forbeing raised and'lowered. Cord receiving recesses 15 and 15 are disposed within the shoes and counterweight cords I'Z'and 13 are disposed therein. The counterweight cords pass over supporting spools .19 and 20 and counterweights 2'1 and 22 are disposed upon the free ends of the counterweight cords. The rails being made of tubular material to accommodate the counterweights therein.

A cabinet 23 is provided and the same has 'a spider 24 adapted to the back of the cabinet.

A journal bolt 25 is secured to the spider '6 and the same passes centrally through the spider 24 and serves as a journal pin for supporting the cabinet and about which the cabinet may be rotated or journaled relative to the spiders. A nut 26 is adapted to the end of the bolt 25 .to permit the removal of the cabinet from the spider 6. Locking notches, here shownras four in number, as illustrated at 2"! in Fig. 12 are provided in the flange 28 of the spider 6 and a locking bolt 29 is adapted for being held in registry with one of the notches through a spring disposed within A pull link 31 is secured to the bolt and extends outwardly through the side of the cabinet and terminates in pull knob 32 to adapt the same to be manually manipulated.

The cabinet is comprised of frame33 that is composed of side and end members. Secondary end members 34 and 35 are disposed within the frame. Winding drums 36 and 37 are disposed within the frame and the same are preferably made of window shade rollers having winding springs 38 disposed therein so that a tension at all times will be maintained upon the fabric wound about the drums. Driving drums 39 and 40 are parallelly disposed to the winding drums and the same are journaled within the end frame 35. Adjustable plates 41 and 42 are adjustably secured to the end plate 34. Each of the end plates has a slot 43, as'illustrated-inFig. 12 and clamping screws 44 and 45 are disposed within the slot and threadably secured to the end bar 34, the

purpose and object of the plates being to provide .compensating means for the vertically disposed rollers. The plates are adjusted to compensate the delineated sheet being wound upon the drums when the same is being wound, while the frame Bin a vertical position. The end'46 and 47 of the respective-drums pass through slots 48 and 49 that are disposed within the end bar 34. One or more delineated sheets v50 are secured upon its respective ends'to the winding drums 36 and 37 and the same pass about the .driving drums 39 and 40. The winding springs disposed within the respective winding drums maintains a suitable tension within the delineated sheet 50 secured thereto. The driving drums :39 and 40 have shafts 51 and 52 downwardly extending .therefrom and driving sprockets 53 and 54 aresecured to the respective shafts. A driving element as a driving chain'55 is trained about the respective sprockets and is adapted for being driven by a driving sprocket 56.' The driving sprocket 56 may be "hand manipulated by a knob 57 that is disposed up on the-outer end of the shaft 58 to which the driving sprocket 56 is secured. The same may be power driven by the mechanism illustrated in Fig. 5. When so driven, a prime mover as an electric motor 59, is used secured to the armature shaft 60 of the prime moverare driving worms 61 and 62, the driving worms being adapted for coacting with and driving the worm wheels .63 and 264. The worm wheels being secured to driving shafts 65 and 66 of the drivcured to the end members '34 and 35 and over which the delineated surface ismade to pass and which supports'the same. A hand engaging knob 69 is disposed at one-end of the cabinet to facilitate the manipulating of the same. A name and advertising plate '70 maybe secured tothe upper cross bar 4 upon which instructions and other matter may be placed describing the operation and use of the cabinet associated therewith. This is particularly desirable where my device is made accessible for use of the public.

While the form of mechanism herein shown and described is admirably adapted to fulfill the objects primarily stated, it is to be understood that it is not intended to confine the invention to the one form of embodiment herein shown and described, as it is susceptible of embodimentin various forms, all coming within the scope of the claim which follows.

What I claim is:

In a device of the class described, the combination of a support, a cabinet rotatably mounted to the'support, a frame vertically disposed within the cabinet and extending lengthwise thereof, said frame comprising a panel having inwardly turned top and bottom end walls, a pair of spaced apart parallel rods extending through said end parallel to the first mentioned rollers, an elon--- gated delineated sheet secured at one of its ends to one of said companion rollers and extending around the roller adjacent thereto thence across the frame and around the corresponding roller on the opposite side of the frame and terminating in attachment to the roller adjacent thereto, said companion rollers being provided with spring tension means to urge their rotation in a direc tion to apply tension on said delineated sheet.
